My current research is about the formation and evolution of the small bodies, moons and planets of our Solar System, focusing on collisional processes. Recent major achievements include:

 

  • Development and validation of a state-of-the-art SPH shock physics code which is specially suited to study the regimes of collisions among small bodies where the complex effects of material strength, friction, porosity as well as self-gravitation determine the outcome concurrently.

 

  • Coupling of 3D planetary-scale impact calculations to long-term interior evolution simulations.

 

 

  • Studies of the effects of global-scale impacts, which modify the physical and thermal state of a substantial fraction of a target body and alter its global shape. Asteroid 4 Vesta, sometimes called a “small planet”, represents a prime example of a body which experienced multiple such global-scale collisions, as suggested by the presence of its huge impact basins in the southern hemisphere.
